This is a sample application created with NodeJS JHipster Official Blueprint (NHipster)

This application was generated using the NodeJS blueprint of JHipster 7.0.1, you can find documentation and help at For any questions you can refer to the stream lead: Angelo Manganiello.


Before you can build this project, you must install and configure the following dependencies on your machine:

  1. Node.js: We use Node to run a development web server and build the project. Depending on your system, you can install Node either from source or as a pre-packaged bundle.

After installing Node, you should be able to run the following command to install development tools. You will only need to run this command when dependencies change in package.json.

npm install
cd server && npm install

We use npm scripts and Webpack as our build system.

Run the following commands in two separate terminals to create a blissful development experience where your browser auto-refreshes when files change on your hard drive.

cd server && npm start
npm start

Npm is also used to manage CSS and JavaScript dependencies used in this application. You can upgrade dependencies by specifying a newer version in package.json. You can also run npm update and npm install to manage dependencies. Add the help flag on any command to see how you can use it. For example, npm help update.

The npm run command will list all of the scripts available to run for this project.

Using Docker to simplify development (optional)

You can use Docker to improve your JHipster development experience. A number of docker-compose configuration are available in the src/main/docker folder to launch required third party services. You can also fully dockerize your application and all the services that it depends on.

For example, to start a mysql database in a docker container, run:

docker-compose -f src/main/docker/mysql.yml up -d

To stop it and remove the container, run:

docker-compose -f src/main/docker/mysql.yml down

For the entire app run:

docker-compose -f src/main/docker/app.yml up -d

For more information refer to Using Docker and Docker-Compose, this page also contains information on the docker-compose sub-generator (jhipster docker-compose), which is able to generate docker configurations for one or several JHipster applications.

JWT authentication and authorization

Congratulations! You've selected an excellent way to secure your NHipster application. If you're not sure what JSON Web Token (JWT) is, please see What the Heck is JWT?

Your app uses, to get and use the token, the server/src/config/application.yml settings:

            # This token must be encoded using Base64 and be at least 256 bits long (you can type `openssl rand -base64 64` on your command line to generate a 512 bits one)
            base64-secret: {yourSecret}
            # Token is valid 24 hours
            token-validity-in-seconds: 86400
            token-validity-in-seconds-for-remember-me: 2592000

You can use the default secret created from the app, or change it. So to get a token, you have to pass a POST request on the api/authenticate url with UserLoginDTO as body. For this you can use swagger ui on /api/v2/api-docs path, or the client login page (if you have generated it).

PWA Support

JHipster ships with PWA (Progressive Web App) support, and it's disabled by default. One of the main components of a PWA is a service worker.

The service worker initialization code is commented out by default. To enable it, uncomment the following code in src/main/webapp/index.html:

  if ('serviceWorker' in navigator) {
    navigator.serviceWorker.register('./service-worker.js').then(function () {
      console.log('Service Worker Registered');

Note: Workbox powers JHipster's service worker. It dynamically generates the service-worker.js file.

Managing dependencies

For example, to add Leaflet library as a runtime dependency of your application, you would run following command:

npm install --save --save-exact leaflet

To benefit from TypeScript type definitions from DefinitelyTyped repository in development, you would run following command:

npm install --save-dev --save-exact @types/leaflet

Then you would import the JS and CSS files specified in library's installation instructions so that Webpack knows about them: Edit src/main/webapp/app/vendor.ts file:

import 'leaflet/dist/leaflet.js';

Edit src/main/webapp/content/css/vendor.css file:

@import '~leaflet/dist/leaflet.css';

Note: There are still a few other things remaining to do for Leaflet that we won't detail here.

For further instructions on how to develop with JHipster, have a look at Using JHipster in development.

Using Angular CLI

You can also use Angular CLI to generate some custom client code.

For example, the following command:

ng generate component my-component

will generate few files:

create src/main/webapp/app/my-component/my-component.component.html
create src/main/webapp/app/my-component/my-component.component.ts
update src/main/webapp/app/app.module.ts

Using NestJS CLI

You can also use NestJS CLI to generate some custom server code.

For example, the following command:

nest generate module my-module

will generate the file:

create server/src/my-component/my-component.module.ts

Building and running


npm run start:app


npm run build:app

The build folder with all compiled sources will be server/dist.

For more explanation about full stack server/client build refer to server/

Client tests

Unit tests are run by Jest and written with Jasmine. They're located in src/test/javascript/ and can be run with:

npm test

UI end-to-end tests are powered by Protractor, which is built on top of WebDriverJS. They're located in src/test/javascript/e2e and can be run in a terminal (npm run e2e) after that the full application is run (npm run start:app).

For more information, refer to the Running tests page.

Code quality

Sonar is used to analyse code quality. You can start a local Sonar server (accessible on http://localhost:9001) with:

docker-compose -f src/main/docker/sonar.yml up -d

You can run a Sonar analysis with using the sonar-scanner. Then, run a Sonar analysis in the server folder:

npm run sonar:scanner

For more information, refer to the Code quality page.
